Which one of the following orders is not in accordance with the property stated against it?
- $F_2 > Cl_2 > Br_2 > I_2$ Oxidising power
- $HI > HBr > HCI > HF$ Acidic property in water
- $F_2 > Cl_2 > Br_2 > I_2$ Electronegativity
- $F_2 > Cl_2 > Br_2 > I_2$ Bond dissociation energy
The Correct Option is D
Solution and Explanation
$F_2 > Cl_2 > Br_2 > I_2$ due to following order of size
$I > Br > Cl > F$.

Haloalkanes and Haloarenes - Classification
Classification of Haloalkanes and Haloarenes are as follows:
Haloalkanes and Haloarenes are Classified on the Basis of the Number of Halogen Atoms:
These are further classified as mono, di, or polyhalogen (tri-,tetra-, etc.) compounds depending on whether they contain one, two or more halogen atoms in their structures. For example;
- Monohaloalkane
- Dihaloalkane
- Trihaloalkane
Haloalkanes and Haloarenes are Classified on Compounds Containing sp3 C—X Bond (X= F, Cl, Br, I)
This class includes:
- Alkyl halides or haloalkanes (R—X)
- Allylic halides
- Benzylic halides
Haloalkanes and Haloarenes are Classified on Compounds Containing sp2 C—X Bond
This class includes:
- Vinylic halides
- Aryl halides
